DETACHABLE VEHICLE-RIM.

Specification of Letters Patent.

Patented Sept. 13, 1910.

Application ied February 28, 1908. Serial No. 418,180.

To all 'whom it mag/concern:

Be it known that I, MARTIN L. WILLIAMS,

`a citizen of lthe United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Detachable Vehicle-Rims, and which refers more particularly to a rim adapted for use with inflated or neumatic tires of various types.

s is well known lautomobiles or other motor vehicles generally carry an extra tire for use in case of4 injury, to any of thosein use. In the case of a A uncture or other injury, however, the injured tire mustI first be freed-from lthe rim, the extra tire then placed upon the rirny and then inflated. These various operations are usually tedious and accom lished under adverse conditions.

Among t e salient objects of the invention are to obviate the aboveA difficulties by providing a detachable rim adapted to be secured to the stationary rim proper and carrying an inflated tire ready for use.

. Other objects of the invention are to provide a device which can be readily rearranlged for use with various types of tires Wit out necessitating material changes in the construction; to provide simple and reliable means for securin a detachable rim in lace upon the whee, consisting essential y of a detachable locking and rim supporting ring; to provide a construction whereby the locking ring may be forced into its assembled position by means of a simple detachable cranked gear; to provide an 1mroved form of locking device for preventlng circumferential movement of the locking ring upon the rim after the device is assembled; and in general to provide an imroved construction of the character reerred to.

The invention will be understood from the following description, reference being had to the accompanying drawings in which- Fi ure 1 is a side elevation of the vehicle whee embodying my invention, parts being broken away to show detailsv of construction. Fig. 2 is a transverse sectional detail of my device in assembled position and ada ted for use with the clencher type of tire. ig. 3 is a view similar to Fiff. 2 but showing the crank gear for forcing the locking ring into place upon the rim, the felly and part of the ,crank socket being shown in side elevation. Fig. 4 is a fragmentary perspective view of the parts in assembled position, part l obliquelly of the locking ring and detachable rim being cut away to show the coperative relations of the various parts. Fig. 5 is a rear ele- `vation of the locking device, the actuating spring being shown 1n dotted lines. Fi 6 is a view slmilar to Fig. 5 taken at right angles thereto.

Referring to the drawings 1 designates as a whole the vehicle wheel providedwith a pneumatic tire 2, the latter being inI the present instance of the well known clencher adapted to support one side of the detachable rim 8, as will hereinafter appear. The

Iother ed e of the inner rim 4 is provided 'with a thlckened portion 7 and in this thick- -ened part of the rim are cut a vseries of bayonet slots 9. These slots extend circumferentially of the rim, are inclined inwardly from said edge and have relative long entrance portions 10.

In or er that the tire may be inflated before assembling, I provide a detachable rim 8, which toget r with its inflated tire may be carried on the vehicle in the same manner as the usual extra Itire. In the present instance the detachable rim is shown as adapted for ,use with the clencher type of tires butl obviously other t pes of tires may be used. This deta'chable rim 8 is adapted to it u on and be supported by the inner rim and is accordingl inclined upwardly near its outer edges to il) 13. When the outer rim 8 is assembled on the wheel, these seat faces are supported yby the elevated extension 6 of the stationary rim and a similarly inclined portion of a locking ring 14 hereinafter described. In order to prevent circumferential movement of the outer rim relatively to the inner one, the outer ed e of the elevated seat surface 6 of the seat ace 13 is provided with one or more studs 17 which register with apertures 18 formed in the elevated support 6.

Describing now the means or locking the outer rim and tire upon the inner rim, 14.

rm annular inclined 'seatfaces inclined inwardly to form a seat surface, an y ing rin is slipped over theedge of the inner rim an the bayonet lugs entered in the entrances 10 of the bayonet slots 9, and the locking ring then rotated into locked position. Inasmuch as these bayonet'slots are inclined inwardly from the outer edge of the inner rim, the rlng will as it is turned into osition -have an axial as well as a circumerential movement. This axial movement will force thek Wedge shaped seat portion 15 of the locking ring between the two rims and thus eifectually wedge the outer rim into place and revent any lateral movement of the tire and, outer rim independently of the wheel proper. As one feature of my invention, means are provided for thus forcing the locking ring into place upon the inner rim. To this `lend I provide a detachable crankear 20 rigid with a crank arm 21, which 1s `adapted'to be detachably journaled in a socket 22 formed in a stud extension 23 fixed to the felly of the wheel. The teeth of the gear mesh with a series of teeth 24 formed upon the inner edge of the inturned flange 19 of the locking ring. As the crank arm 21 is rotated, gear 20 meshing with the teeth on the flan e 19 of the locking ring obviously turns t e locking ring u on the inner rim until theribs 9 have su ciently enteredtheir respective bayonet slots. After the locking ring is forced into place, the crank arm may be slipped out of the socket and stored away the vehicle.

In order to obviate any danger 0f the locking ring sli ping circumferentially upon the inner rim a ter the device is assembled, I provide a lockingv device designated as a whole 25- which is secured to the stationary rim 4. This locking device comprises a base plate 26 secured to the inner rim, and

rovided vwith a pair of upstanding ears 27 tween which is pivotally mounted a s ring pressed locking lever 28. One end o this ever is provided with a handle 29 while the other end is adapted to register with one of a series of recesses 30 formed on the lower scanso edge of the annular flange 19 of the locking ring. The lever is held in its locked position by means of a plate spring 31 seated between the ears 27. i

While I have herein shown'and described a preferred embodiment of my invention it is obvious that the exact details of construction are not essential in the broader aspects of the invention.

I claim as m invention:

1. In a vehicle wheel, the combination with an inner rim having an inclinedbearing surface `at one side thereof, a detachable outer rim supported at one side vby said bearing surface, a wedge shaped locking ring having an inclined bearing surface supporting the other side of said outer rim, a downturned flange upon the outer edge of said locking ring, bayonet joint connections between the outer dperiphery of saidf inner rim and the oppose ring comprising a plurality of spaced apart lugs upon the inner face of said locking ring, and coperating recesses or slotsupon the u per face of the stationary rim, said slots eing open at one end to permit the entrance of said lugs, and vmeans coperating with the downturned flange of said locking ring to force the latter into positionA upon the inner. rim.

2. In a vehlcle wheel, the combination with an inner rim having an inclined bear-` periphery of said locking ing surface at one side thereof, a detachable y outer rim supported at one side by said bearing surface, a wedge shaped locking ring havingv an inclined bearing surfacesupport'- ing the `other sideof said outer rim, a downturned flange upon the outer edge of said locking ring, bayonet joint connections between the outer dperiphery of said inner rim j and the oppose periphery of said locking ring comprising a plurality of spaced apart lugs upon the inner face ofv said locking ring,'and coperating recesses or slots upon the u per face of the stationary rim, said slots cing open at onev end to permit the entrance of said lugs, and a cranked-gear detachably journaled in the felly of the wheel,

and coperating with the downturned ange,

of said locking ring to force the latter into position upon-the inner rim.
